The directives and manuals, which for more than a decade directed the US military’s policy for treatment of its detainees, will be released chronologically over the next month, WikiLeaks said in a statement.

The first batch of the documents released is the 2002 Camp Delta – Guantanamo Bay prison – Standing Operating Procedure manuals.

“This document is of significant historical importance. Guantanamo Bay has become the symbol for systematized human rights abuse in the West with good reason,” WikiLeaks founder Julian Assange said.

Several of the documents slated for publishing “can only be described as ’policies of unaccountability,’” WikiLeaks said in its press release.

One document such document that has been previewed but not yet published is the ’Policy on Assigning Detainee Internment Serial Numbers’. Wikileaks claims it is a manual on how to “disappear” sensitive prisoners “by systematically holding off from assigning a prisoner record numbers”.

Another apparently contains the notorious instructions to “purge” interrogations tapes, which became notorious following the Abu Ghraib torture scandals in the mid 2000s. WikiLeaks called on NGOs, activists and the general public to thoroughly read the documents to gain a better understanding of the evolution of the Pentagon’s post-9/11 attitude towards prisoners.
